Be it known that I, STANISLAW A. Kori- TONSKI, a subject of the Czar of Russia, residing in Boston, in the county of Su'll'olk and State of llflassachusetts, have invented a new and useful Improvement in Telephones, Particularly for Interior Use, of which the following is a specification.

My invention relates to a telephone switch device.

My invention consists in new structures or parts and in new combinations of the structures, as will be more "fully shown by reference to the drawings, in which- Figure 1 is a top plan of a telephone-box, partly broken away, and of the arm on which the telephonereceiver is hung. Figs. 2 and 3 are plans of the push-buttons and. contactsprings. Figs. 4 and 5 are views, partly in cross-section, showing the push-buttons, locking and unlocking devices, and base. Fig. 6 is a side view, partly in section, showing two push-buttons, their circuit connections, and the base. Figs. 7 and 8 are details showing the form and structure of the two latches. Fig. 9 is a detail in cross-section of the top plate, insulator, and under plate constituting the ringing-circuit. Fig.

10 is a diagram. illustrating the circuit and circuit connections.

The box and ordinary switch mechanism, a form of which is illustrated in Fig. 1, together with the telephone-receiver hook Y, by aid of which also a circuit may be made and broken, and its connections with the circuits, and the circuits themselves are too well understood in the art to require any further description than will be made in describing my improvements.

In the drawings, A represents the ordinary telephone switch-box.

B, Fig. 6, is the support therein for the mechanism.

0 C are the push-buttons pivoted at 1 to the latches D D and preferably loosely pivoted to meet any shrinkage or displacement of the cover of the box. The latches D D are placed above the pillars E E, having shoulders grooved, as shown, Fig. 4C, for the guidance of the latches. The extensions of said pillars a ove the shoulders are surrounded by the coiled springs e 6, whose function is to press out the push-button mechanism when released. The two latches D D to which are loosely pivoted. at 1 the push-buttons C, have a center projection d, fitting down into the helical springs e a, mounted thereon. The latch D carries on d the insulating-cam. (1", located behind the circuitsprings c g and immediately above the circuitsprings (1/ I), shown, Fig. 6, whereby depression of the push-button will by means ol the insulating-cam (Z first crowd the springs a 1) into contact with the springs c g, then. separate said springs, then crowd the springs c g into contact with the ringing-circuit I H; but, as shown, Fig. 2, upon removal of pres sure the cam 61 returns until the nose (Z (which, as shown, Fig. 8, is bent out of plane with the main body of the latch) locks on the l ar F, as in Fig. 5, thus separating springs c g from I H, leaving springs c gin contact with springs a b as shown, Fig. 3. The latch D carries on its arm (.Z a similar insulating-cam which operates in a similar way It will be understood that any number of push-buttons and latches may be used in corn nection with the bar about to be described. The locking-bar F serves the purpose of two bars in connection with any desired number of the latches and is mounted on the supports f f, Fig. 6, and connects by its arm f with the arm rigidly pivoted to the receiverhook arm Y. The armf is connected to the arm f 2 by an angle lever-hookf which is loosely pivoted at its angle on the arm/' so that when the arm Y is brought down by the receiver the hook part Off moves the armj", which arm in moving disengagcs the latches D D, and thereupon the hook part of 3 swinging on its pivot and its other arm abutting against the stop rises above arm f, which thereupon returns to its position by aid of a proper spring. (Not shown.) This bar F passes within the space 2 of the latch D and the space 2 of the latch D, Figs. 7 and 8.

In Fig. 10 it will be seen that the circuitwires 0 g are attached to the springs c g and Wires a b to the springs a b.

I will now describe the operation 01 my apparatus, which is shown in normal condition out of use in Fig. 6. The party desiring to call any one of the numerous stations with which he is connected presses upon a pushbutton corresponding with the desiredv station, whereupon the springs c 9 contact with l i, esml lisliin iie ringi n I "teliingno e,
